awk printf ignoring '\n'

Hi group,
I just installed Debian and ran into this problem.

When I run this bash script that calls awk, all the output is on a single line.

Code:

#!/bin/bash

IP_Text=`/sbin/ifconfig |          \
  awk '{ ORS = "\n\n" }{           \
  if($0 ~ /Ethernet/ ||            \
     $0 ~ /Point-to-Point/ ) {     \
    printf("%s:", $1);             \
    Line=getline;                  \
    Line=$2;                       \
    if(Line ~ /addr/ ) {           \
      n=split(Line,Array,":");     \
      printf("%s\n\n",Array[2]); } \
    else {                         \
      printf("None\n\n"); }        \
print "Done\n"; } }'`

echo ${IP_Text}

The output looks like this:

Code:

$ IP_Addr
eth0:None Done ppp0:66.81.51.154 Done

I'm running mawk 1.3.3 Nov 1996, Copyright (C) Michael D. Brennan

Any ideas??

Try echo with quotes:

Code:

echo "${IP_Text}"

That works, thanks.
